Should I tell my MIL about our miscarriage?

We had a miscarriage last month and the only people who know are my parents and my best friend. My husband and I don’t have the strongest relationship with his parents. I have been debating if I should tell them or not.

My MIL is very dramatic and likes to gossip I just feel like she is going to some how make it all about her (if that makes sense) and she is going to tell everyone. I’m not ready for everyone to know and I just can’t deal with the emotions im having as well as her emotions.

We are currently trying for our rainbow baby so I’m not sure if I should just not tell her. Or maybe tell her in a few months. I’m just worried that if I wait to tell her then she will make a bigger deal and be upset that she didn’t know.
